Introduction
- Health and economic indicators help compare country performance.
- Multiple variables can be difficult to analyze together.
- Parallel coordinates plot helps visualize multivariate data.
Objective
- Analyze country-level indicators
- Compare:
- Total Quantity
- Average Unit Price
- Total Sales
- Use R for visualization
Data Overview
- Dataset contains transaction-level data
- Key variables:
- Quantity
- Unit Price
- Country
- Aggregated into country-level indicators
Data Preprocessing
Before analysis, the dataset is cleaned and prepared. Column names are standardized, and missing values are handled to ensure accuracy. This step improves data quality and makes it suitable for visualization.
Visualization
-Parallel coordinates plot used. -Each line represents a country. -Values are scaled between 0 and 1. -Helps compare multiple indicators at once.
Insights
-High quantity ≠ always high sales. Pricing plays a key role in total revenue. Balanced indicators lead to better outcomes.
